To all whom it may concern.-

Be it known that we, FREDERIoK E. NEL- SON and GEORGE W. TRIBBEY,citizens of the United States, and residents of Marshfield, in thecounty of Coos and State of Oregon, have invented certain new and usefulImprovements in Gates, of which the following is a specification.

Our invention relates to improvements in gates of that character inwhich a sliding weight traversing an oscillatory bar is used to causethe gate to swing in either direction to open and close the same.

The object of our invention is to provide a simple, cheap, and efficientgate of the character described which can be readily operated to openand close at a considerable distance from the gate, whereby thenecessity of leavingda vehicle approaching the gate is obviate To theseends our invention consists in certain novel features of construction,arrangement, and combination of parts, as will be hereinafter fullydescribed, and pointed out in the drawings, in which Figure 1 is a sideelevation of a gate and attachments, showing a practical embodiment'ofour invention. Fig. 2 is a detached view of the oscillatory bar andweight used to give the gate its swinging movement. Fig. 3 is an endelevation, partly in section, of the operating devices as applied to agate-post. Fig. 4 is a detail perspective view of the means for hingingthe upper end of the gate to its post and the means for causing the gateto swing. Fig. 5 is a detail plan of the upper casting or hinge of gate.Fig. 6 is a side elevation of the lower swing-link. Fig. 7 is a sideelevation of the lower casting or hinge.

In carrying out our invention a post A of suitable height is used,having attached to its lower portion a suitable distance above theground the casting B, provided with the vertically-projecting pintle Z),upon which is rotatably fitted the enlarged end a of another casting C.The smaller portion of casting 0 projects from the enlarged portion 0and has projecting from its upper face a pin 0.

D is another casting secured to the post A, having a projecting eye d,and from this eye d projects an offset eye (1.

E is a plate secured to post A above casting D and has projecting fromits outer face the stud e, which has its free end 6 reduced andthreaded.

F is a rod rigidly secured at its lower end to the enlarged portion 0 ofcasting O and passes upwardly through eye upper end of rod F is madeinto the form of or has secured to it a segmental miter-gear G, whichengages and meshes with a similar segmental miter-gear H at the centerof slotted arm H, which is pivotally mounted on the reduced end e of thestud e, projecting from plate E, and is held thereon by a nut e or othersuitable means. The bar H, as stated, is slotted, its slot h extendingfrom a point near one end to a point near its opposite end, each end ofthe slot it being enlarged, as at h I is a weighted slide embracing thesides and top of the bar H, being held to said bar by a pin "L passingthrough the slot h and through the side members of said slide.

J is a rope or cable secured at one end in an eye i, projecting from theupper face of slide 1, said rope or cable extending upwardly a suitabledistance and then dividing into two ropes or cables J J and diverging,thence passing over sheaves K K, suspended from arms L L, secured to andprojecting from the upper end of post A.

M is the rear bar of the frame of the gate N, said bar M being rotatablymounted at its lower end on the pin 0 of casting C. The upper end of barM passes through the offset eye cl of casting D, said eye (1 beingsufficiently large to permit of the rotating and.

tilting motion of said bar M. The gate proper is of metal, preferably,and consistsof the front and rear vertical bars, the horizontal upperand lower bars, and cross wires or rods, and is provided with a latch P,engaging a keeper Q on the post R.

The .operation of our gate is as follows: With the parts in positionindicated in full lines, Fig. 8, the gate is closed. If now a pull ismade on the rope J from either branch rope the pin or bolt & of theweighted slide I will be drawn up into the enlarged end h of the slot hand will raise the right-hand end of the bar H, causing it to swing onstud e, the segmental gear H meshing with segmental d of casting D. The

gear G on the upper end of bar F and rotating said bar F. As the lowerend of bar F is rigidly attached to the member or link 0 andO ispivotally mountedat one end on the pin 1) of casting B, the free end ofthe link is carried past the vertical center of bar F, and the upper endof bar M fitting loosely in the oil"- set eye d and its lower endswiveling on pin the gate will tilt and release the latch, thuspermitting the gate to swing open. If now the rope or cable is released,the bolt i of weighted slide I drops out of the notch h and immediatelyslides to the opposite end of'slot it, so as to be in readiness for thenext pull to swing the gate to its closed position, as indicated inbroken lines, Fig. 3.

It will thus be seen that we provide simple, cheap, and eflicient meansfor opening and closing a gate from either side at a considerabledistance and with the expenditure of very little labor.

We claim 1. In combination with a gate-post, a casting secured to thepost near its lower end and having a vertically-projecting pin, a linkpiv- .otally mounted on said pin, said link having avertically-projecting stud or pin, a rod or bar rigidly secured to oneend of said link and projecting upwardly, a casting secured to the postand surrounding the aforesaid rod near its upper end, said rod having atits upper end a miter-gear, a gate the rear bar of which is pivotallymounted at its lower end on the vertical pin of the link, and passes atits upper end through an eye offset to one side from the upper casting,a stud projecting from the gate-post, a bar pivotally mounted at itscenter on said stud, said bar having a segmental miter-gear on its loweredge meshing with the gear on the aforesaid rod, a weighted blockmounted to slide on said pivoted bar, and means connected with saidblock to cause the bar to swing on its pivot, and rotate the rod havingthe 1niter-gear at its upper end and through the link at its lower endcause the gate to tilt, and unlatch and swing open or closed.

2. The combination with castings secured to said gate-post carrying theupper and lower ends of the rear bar of the gate, the lower castingprovided with a vertically projecting pin, and the upper castingprovided with two eyes, one of which is offset to one side, a linkpivotally mounted on the pin of the lower casting, a vertical rodrigidly secured at its lower end to one end of said link and projectingthrough one of the eyes of the upper casting, and a miter-gear at theupper end of said rod, a pin or stud projecting upwardly from the link,a gate, the rear bar of which is pivotally mounted at its lower end onthe pin projecting from the link and passes at its upper end through theoffset eye of the upper casting, a horizontal stud projecting from thegate-post, a slotted bar a gate-post, of

pivotally secured at its center on said stud, a segmental miter-gear onthe lower edge of said slotted bar, the slot of said bar having offsetbranches at each end, and the segmental gear on said bar meshing withthe mitergear on the upper end of the aforesaid rod, a weighted blockmounted to slide on said bar being guided by said slot, and meanssecured to said block to cause the slotted bar to swing on its pivot tocause rotation of the rod carrying the miter-gear at its upper end, andcause the link secured to its lower end to oscillate to one side of thevertical center of said rod and tilt the gate to unlatch the same andcause it to swing open or closed.

3. In combination with a gate and a post to which said gate is pivotallysecured, of a rod mounted between said gate and post, a pivotalconnection between the lower end of said rod and the lower rear end ofthe gate, a pinion secured to the upper end of said rod, a bar pivotallysecured intermediate its ends to the gate-post adjacent to said pinion,a gear-rack projecting from said bar and engaging said pinion, a blockslidably mounted on said pivoted bar, and means for sliding said blockon the bar to cause the same to rock on its pivot, and rotate the rodcarrying the pinion, whereby said rod will cause the gate to swingbeyond its vertical center and tilt the same to cause it to unlatch andswing open and closed.

4. In combination with a gate and a post to which said gate is pivotallysecured, a vertical rod mounted between said gate and post, a castingsecured to the post adjacent to the to the post and embracing the upperend of the aforesaid rod, an eye projecting obliquely to one sidefrom'said upper casting and loosely embracing the upper end of the rearupright of the gate, a link-iron pivotally mounted on the lower castingand rigidly secured to the lower end of the rod mounted between the gateand post, said link having a pivotal connection with the lower end ofthe rear upright of the gate, a pinion secured to the vertical rod at ornear its upper end, and a toothed rack meshing with said pinion wherebythe pinion and the vertical rod to which it is secured may be rotatedand cause oscillation of the link-iron and thereby swing the rearupright of the gate beyond its vertical center, whereby the gate will betilted to unlatch and swing open or closed.
